What MA83 means

The claim did not say whether this payer is primary or secondary, so it could not be processed correctly.

The payer needs to know where it sits in the order of coverage. This remark says the claim did not show whether it was the primary or secondary payer.

It usually comes with reason code 16. Correct the payer responsibility sequence and send the claim again.

Common causes

• The payer responsibility sequence was left blank in the claim file.
• Other coverage was reported but the claim did not mark which payer this one was.
• The patient's insurance setup in the billing system had no order assigned.

What to do next

1. Confirm the order of coverage with the patient and payers.
2. Set the primary and secondary order correctly in the patient's insurance record.
3. Resubmit the corrected claim with the payer order clearly set.
